Don't think that DxO, DPR, Photozone, etc. are wrong, but it seems that their MTF-50 results don't tell the whole story. Maybe the 7D would have a higher resolution than the 5D if using MTF-5 instead of MTF-50, but that wouldn't tell the whole story either (so maybe it would be a good idea to use both).

Exactly. In the old times, DXOmark had the whole MTF curves. In typical cases, the 5D would be better down to MTF-10 or so, and below that, the 7D would be better - just because it has a larger Nyquist frequency. They did not measaure anything below MTF-5, if I remember it correctly, because then the noise and all errors overtake.

In other words, the 5D would be better in the MTF 10-95 range, and the 7D: in the MTF 5-10 range, roughly speaking. There are lot of other variables though, lenses used, apertures, etc.

Here is a typical chart but there are no labels here. It is not clear what we are looking at.
